I have one inline with a very sharp and very tight threads... The only tape I can use on it is the white tape and only one wrap...

On my breech plugs I do dull the threads and remove the machining burrs by turning in a piece "scotch brite" with a ratchet. By polishing and removing the burrs - the tape does not get torn going in..

The new TC breech plugs with the "O" ring seal do not require anything but taking care of the "O" ring...
